[PATCH] ia64: Fix incorrect return value from ia64_setup_msi_irq()

[Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com>]

Hi,

Here is a patch to fix the problem that pci_enable_msi() always fails
on ia64 platform.

Thanks,
Kenji Kaneshige

Fix the problem that pci_enable_msi() fails on ia64 platform. The cause of
this problem is incorrect return value of ia64_setup_msi_irq(). It must
return 0 on success, instead of irq number.
